What makes something addictive?
What spins in your head and the edges of your tongue, something that's just on the tip of your nose.
That kind of thing!
For me it's Utz potato chips and Utz sour cream and onion dip, though now they unfortunately just sell "onion dip" in my area.
There's also really good sushi and very good steak and all kind off things, not to mention booze. What brings you back, like a serious addiction.
